Montarello and Martens

14.   Montarello and Martens (2005) found that fifth-grade students completed more mathematics problems cor- rectly when simple problems were mixed in with their regular math assignments. To further explore this phenomenon, suppose that a researcher selects a stan- dardized mathematics achievement test that produces a normal distribution of scores with a mean of

m 5 100 and a standard deviation of s 5 18. The researcher modifies the test by inserting a set of very easy problems among the standardized questions, and gives the modified test to a sample of n 5 36 students. If the average test score for the sample is M 5 104,

is this result sufficient to conclude that inserting the easy questions improves student performance? Use a one-tailed test with a 5 .01.
